Abstract

The utility model discloses a car frame speed limiting device which comprises ratchet wheels and pawls, wherein the ratchet wheels are arranged by being coaxial with car frame diversion sheaves; the pawls are rotatably arranged on the car frame diversion sheaves and can rotate to be inserted into tooth sockets of the ratchet wheels when the car frame diversion sheaves are in overspeeding; a safety tongs draw bar is rotatably arranged on the radial surface of one ratchet wheel; when a lift is in overspeeding, the car frame diversion sheaves are also in overspeeding correspondingly, so that the pawls are clamped into the tooth sockets of the ratchet wheels after rotating, thus the ratchet wheels rotate correspondingly along with the rotation of the car frame diversion sheaves, and the rotating ratchet wheels draw the safety tongs draw bar so as to draw safety tongs to act so as to stop a lift car in time and play a protective role. The car frame speed limiting device has a simple structure and is low in manufacturing cost, and parts such as a steel wire rope and a balancing weight of the speed limiting device are omitted.

Description

A kind of sedan-chair frame speed-limit device
Technical field
The utility model relates to a kind of sedan-chair frame speed-limit device.
Background technology
Existing sedan-chair frame speed-limit device, be comprised of a plurality of parts such as speed limited wheel, tension wheel, speed limiter wire rope, clump weights, timely stop sedan-chair frame or car while realizing elevator overspeed, but existing speed-limit device complex structure, and cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, sedan-chair frame speed-limit device that cost is low.
﹠lt, b TranNum="67" ﹠gt, for achieving the above object, the technical solution adopted in the utility model is: a kind of sedan-chair frame speed-limit device, comprise sedan-chair frame diversion sheave, being contained on the sedan-chair frame can stop sedan-chair frame or the safety tongs of car, can drive the safety tongs lifting rod of described safety tongs action with the described sedan-chair frame of stop or car, described sedan-chair frame speed-limit device also comprises the ratchet with the coaxial setting of described sedan-chair frame diversion sheave, thereby rotation is arranged on described sedan-chair frame diversion sheave the ratchet in the teeth groove that inserts described ratchet that can rotate when this sedan-chair frame diversion sheave hypervelocity, described safety tongs lifting rod rotates and is arranged on the radial surface of described ratchet, the rotational axis line of described safety tongs lifting rod, the rotational axis line of described ratchet all departs from the axial line of described ratchet, and all with the axial line of this ratchet, parallel, described sedan-chair frame diversion sheave has normal condition and overspeed condition, when described sedan-chair frame diversion sheave is in normal condition, ratchet on this sedan-chair frame diversion sheave breaks away from the teeth groove of described ratchet, it is motionless that described ratchet keeps, when described sedan-chair frame diversion sheave was in overspeed condition, described ratchet inserted the teeth groove of described ratchet, and described ratchet is along with described sedan-chair frame diversion sheave rotates, by lifting the action of described safety tongs lifting rod and described safety tongs, and the described sedan-chair frame of stop or car.</b>
During concrete enforcement, described ratchet is positioned at the outside of described ratchet.
Utilization due to technique scheme; the utility model compared with prior art has following advantages: this sedan-chair frame speed-limit device; adopt coordinating of ratchet and ratchet and ratchet and safety tongs lifting rod; make when elevator overspeed; corresponding to sedan-chair frame diversion sheave also overspeed rotation; snap in the teeth groove of ratchet after ratchet rotates; like this along with the rotation of sedan-chair frame diversion sheave; ratchet is corresponding the rotation also; the ratchet that rotates lifts the safety tongs lifting rod, and lifting rod lifts safety tongs, makes the safety tongs action; in time the stop car, play a protective role.This sedan-chair frame speed-limit device is simple in structure, has saved the parts such as speed limiter wire rope, clump weight, low cost of manufacture.
Description of drawings
Accompanying drawing 1 is schematic diagram of the present utility model.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
﹠lt, b TranNum="79" ﹠gt, shown in Figure 1, a kind of sedan-chair frame speed-limit device, comprise sedan-chair frame diversion sheave 2, being contained on the sedan-chair frame can stop sedan-chair frame or the safety tongs 4 of car, can drive the safety tongs lifting rod 3 of safety tongs 4 actions with stop sedan-chair frame or car, ratchet 1 with the 2 coaxial settings of sedan-chair frame diversion sheave, thereby rotation is arranged on sedan-chair frame diversion sheave 2 ratchet 5 in the teeth groove that inserts ratchet 1 that can rotate when this sedan-chair frame diversion sheave 2 hypervelocity, ratchet 5 is positioned at the outside of ratchet 1, although ratchet 1 and the 2 coaxial settings of sedan-chair frame diversion sheave, if but there is no the cooperation of ratchet 5, ratchet 1 is to separate independent the setting with sedan-chair frame diversion sheave 2, be that sedan-chair frame diversion sheave 2 is while rotating, ratchet 1 can and then not rotate.safety tongs lifting rod 3 rotates and is arranged on the radial surface of ratchet 1, the rotational axis line 8 of safety tongs lifting rod 3, the rotational axis line 9 of ratchet 5 all departs from the axial line 7 of ratchet 1 or sedan-chair frame diversion sheave 2, and all with the axial line 7 of this ratchet 1 or sedan-chair frame diversion sheave 2, parallel, traction steel-cable 6 is walked around sedan-chair frame diversion sheave 2, when elevator normally moves, be in normal condition corresponding to sedan-chair frame diversion sheave 2, ratchet on this sedan-chair frame diversion sheave 25 breaks away from the teeth groove of ratchets 1 at this moment, even sedan-chair frame diversion sheave 2 rotates, it is motionless that ratchet 1 also keeps, the safety tongs lifting rod 3, safety tongs 4 all is failure to actuate, guarantee that elevator normally moves, when elevator overspeed the time, corresponding sedan-chair frame diversion sheave 2 overspeed rotation, be in overspeed condition corresponding to sedan-chair frame diversion sheave 2, and the speed limiting mechanism that is installed on sedan-chair frame diversion sheave 2 inside this moment makes ratchet 5 actions, after rotating, ratchet 5 snaps in the teeth groove of ratchet 1, along with the rotation (clockwise rotating in Fig. 1) of sedan-chair frame diversion sheave 2, ratchet 1 is corresponding the rotation also like this, and the ratchet 1 of rotation lifts safety tongs lifting rod 3, lifting rod 3 lifts safety tongs 4, make safety tongs 4 actions, in time the stop car, play a protective role.The sedan-chair frame speed-limit device of this patent is simple in structure, has saved the parts such as speed limiter wire rope, clump weight, low cost of manufacture.</b>
